WIRE-DRAWING MACHINE.

y No. 796,261.

To all whom it may concern.

Be it known that I, ANTHONY SMITH, a citi` zen of the United States,residing at Trenton, in the county of Mercer and State of New .I ersey, have invented a new and useful W ire-y Drawing Machine, of which the following is .a specification.

This invention is a machine for drawing wire, the object being to provide a simple and eiicient machine by means of which wire can be drawn to any degree of iineness, and a still further object is to provide a machine in Which the drawing operation can be quickly andl lication, Figure l is a perspective view of a wire-drawing machine constructed in accordance with my invention. Fig. 2 is a side el'evation of the same.. Fig.- 3 is a top plan view. Fig. 4 is a sectional view taken through the die-holder. Fig. 5 is a sectional view taken through the die-holder, said section being in a plane at right angles tothe plane of Fig. 4. Fig. 6 is a detail perspective view of the holder adapted to contain the first or starting die. Fig. 7 is a view. illustrating in perspective and section the construction of the drawing-dies. Fig. 8 is a detail perspective view of the wiregripping device, and Fig. 9 shows relative positions of the lever-jaws during the gripping and pulling operations.

In carrying out my invention I employ a y skeleton base A, to which is bolted an'upright skeleton frame B and also the skeleton brackets O and D. A horizontal shaft E is journaled in the brackets C and D and carries a fast pulley F and a loose pulley F'. A second horizontal shaft G is journaled also in the 4journaled in skeleton frame B and carrying the combined drawing and winding drums N upon its upper end. These combined drawing and winding drums comprise the upper portion N', upon which the wire is wound -Specication of Letters Patent.

Application led January 19,1903. Serial No. 139,604.

after being drawn to the proper degree of ineness', the extreme end of the wire being connected to the winding-drum by runningv the end through a perforation N2. The winding-drum is tapered in stepped order, each portion being separated from the other by means of collar N3,`and it will be noted that thepupper portion N' is larger in diameterV than the uppermost section of the lower part. v

This construction provides a uniform tension upon the wire during the drawing operation'.

The opposite end of the skeleton frame B is formed witha bracket B', in which is mounted a series of guide-rollers O, said rollers being arranged one above the other and all vjournaled upon a common shaft O', and these guide-rollers O are independent of each other in reference to their movements. Mounted upon the skeleton frame B between the draw-y ing Vand winding drums and theguide-rollers is the die-holder P, divided longitudinally, as

shown at P', to permit the passage of the wire,

and slotted transversely, as shown at P2, to receive the drawing-dies Q, which are arranged oneabove the other, vthe broadest gage die being arranged lowermost, as most clearly shown in Figs. 4 and 5. The holder P is bolted tothe top of the frame B and projects upwardly inan oblique position, so as to hold the drawing-dies in proper alinement with the spool N, it being necessary, of course, to

have the longitudinal slot P' oblique inorder to correspond with the stepped winding-drum N. A winding-drum R is mounted upon the end of the shaft G which projects through the frame B, the face of the drum being cut away, as shown at R', and connected to the pulley at the point where it is cut away is the wire-gripping device S, comprising two levers S', formed with gripping-jaws S2, the ends of said levers being obliquely slotted in reverse directions, as shown at S3, the connecting-bolt S4 passing through said slots and connecting the gripping device to the cut-away face of the drum. A dependipg die-holder T is connected to the frame B adjacent to the bracket lB' and is adapted to hold the first die through which the wire is passed while a suiicient amount of wire is wound upon the drum R to start the machine. Power is applied to the fast pulley F and rotates the shaft E, said shaft transmitting its power through the pinion I and gear H to the shaft G, which causes the drumRto rotate in the proper direction after winding a sufficient quantity of wire thereon to start the machine. After a suiiicient quantity of wire has been wound upon the drum R to start the machine the proper dies are arranged in the holder P and the wire run therethrough, the free end of the wire being connected to a winding-drum N at the upper portion thereof. The machine is then started and run at the proper rate of speed, and the wire U will be rolled off from the main reel, (not shown,) drawn through theseries of dies, and Wound upon the combined winding and drawingdrum. The machine is provided with a suitable belt-shifting device, by means of which the belt can be thrown from the fast to the loose pulley, said belt-shifter comprising a rod V, having collars V mounted thereon, said rod being connected to a lever-arm V2, mounted upon the end of a rock-shaft V3, having a treadle Vi arranged thereon, and by pressing on this treadle with the foot the belt can be shifted to either pulley desired.

It will thus be seen that I provide an eX- ceedingly simple and efficient construction of wire-drawing machine by means of which the wire can be quickly and easily drawn to the desired degree 0f fineness and one in which the starting operation can be accomplished drum and a winding-drum, a single series o guide-rollers independently mounted and having a common aXis, a die-holder intermediate said drawing and winding device and said guide-rollers and a series of dies in said dieholder, substantially as described.

3. In a wire-drawing machine, the combination of asingle unitary drawing and winding device consisting of a stepped drawingdrum and a winding-drum having a common vertical aXis, a single series of independentlymounted guide-rollers, a die-holder slotted at right angles and located intermediate said drawing and winding device and said series of guide-rollers, a series of dies in said dieholder, and means for rotating said drawing and winding device, substantially as dcscribed.

4. In a wire-drawing machine, the combination of the frame, a horizontal drivingshaft, a vertical shaft, intel-meshing,r gear between said driving-shaft and said vertical shaft, a unitary drawing and winding device mounted axially on said vertical shaft and consisting of a stepped drawing-drum having collars located between the steps thereof, and a winding-drum above said drawingdrum, a single series of guide-rollers independently mounted and having a common vertical axis, a die-holder mounted on said frame intermediate said drawing and winding device and said series of guide-rollers, said die-holder being slotted at right angles, and a series of dies in said die-holder, substantially as described.
